GEORGE J. PIKE, 0F GRAND RAPIDS, MICHIGAN, ASSIGNOR TO THE W. H.GUNLOCKE CHAIR CO., A CORPORATION OF NEW YORK.

CHAIR.

Application filed April 2, 1917.

To all whom it may concern:

Be it known that I, Gnonon J. PIKE, a citizen of the United States,residing at Grand Rapids, in the county of Kent and State of Michigan,have invented new and useful Improvements in Chairs, of which thefollowing is a specification.

The present invention relates to chairs, and its object is to provide animproved chair back which shall be strong and which may be readily andeconomically manufactured, and also to provide an improved me hod formaking chair backs.

This object is attained by the structure and process hereinafterdescribed, such structure being illustrated in preferable form by theaccompanying drawings, in which Figure 1 is a side view of a chair;

Fig. 2 is a view in perspective of the upper member of the chairs back;

Fig. 3 is a like view of the same after its lower edge has been cutaway;

Fig. 4 is a like view of the lower member of the chairs back;

Fig. 5 is a like view of the same after its upper edge has been cutaway; and,

Fig. 6 is a vertical central section of the chairs back.

The chair 1, having the seat 2 and pedestal 3, is provided with my chairback 4, whose extremities, in the construction shown, extend on eitherside to form the arms 5. This back may be supported on the seat, as inthe construction illustrated, by the stumps-one appearing at 6and by7suitable rods or spindles, as that shown at The chair back is made inthe following manner: Two members, being an upper member 8 and a lowermember 9, are fashioned in arcuate form as shown in Figs. 2 and 4, as bysteaming and bending wooden strips which may be of uniform width andthickness. The lower edge of the upper member and the upper edge of thelower member are cut away so that the portion removed from each memberdecreases from a maximum depth at the middle of said member toward itsextremities. The line of such cutting away as to the upper member 8 isshown in dotted lines 10 in Fig. 2, said member after being so out beingillustrated in Fig. 8; while the line of cutting as to the lower memberis shown in dotted Specification of Letters Patent.

Serial No. 159,088.

lines 11 in Fig. a, said member after being so cut being illustrated inFig. 5.

The members thus prepared are securely joined together, the lower edgeof the upper member to the upper edge of the lower member, as by gluingand by the dowels 12 and screws 13, all illustrated in Fig. 1. Thisdone, the concave surface of the united members is preferably dressed ortrimmed down to the dotted line 14 in Fig. 6 along and adjacent to theirmeeting line, so as to remove the angle formed at said line and providesmooth inner surface of the chair back. The united members may betrimmed into a desired contour, as shown at the upper edge 15 of thechair back in Fig. 1. It will be seen that this construction of thechair back with its chair arm extensions lends itself readily to thepositioning of the middle or rear portion at a higher level above theseat than the extremities or arm portions thereof, as shown in Fig. 1.

The invention being intended to be pointed out by the claims, is not tobe limited to or by details of construction shown or described.

I claim:

1. The method of making a chair back which consists in forming twoarcuate members, then cutting away those edges of the members which areto be joined together so that each cut-away portion decreases from amaximum depth at the middle of the member from which it is out towardits extremities, and then joining the upper edge of the lower member andthe lower edge of the upper member securely together.

2. The method of making a chair back which consists in forming twoarcuate members, then cutting away those edges of the members which areto be joined together so that each cut-away portion decreases from amaximum depth at the middle of the member from which it is out towardits extremities, then joining the upper edge of the lower member and thelower edge of the upper member securely together, and then trimming downthe concave surface of the united members at and adjacent to theirmeeting line.

3. A chair back comprising two arcuatemembers securely joined togetherat their edges, the meeting edges having been cut away so that eachcut-away portion decreases from a maximum depth at the middle of themember from which it is cut toward its extremities.

l. A chair back comprising two arcuate 5 members securely joinedtogether at their edges, the meeting edges having been cut away so thateach cut-away portion decreases from a maximum depth at the middle ofthe member from which itis cut to- Ward its extremities, and the concavesurl0 face of the united members being trimmed down at and adjacent totheir meeting line.

In testimony whereof I have hereunto set my hand.

GEORGE J. PIKE.
